Hi Giuseppe,

thanks, for me a first and so far good impression. Settings seem to make sense from the point of view of someone loosely following discussion.

You correctly state that future testing closer to standard network conditions would be interesting (bigger RTT, smaller bottleneck bandwidth). Overall buffer depth information would be interesting too. "Standard test conditions" to compare the performance of different ECN marking related approaches might make sense.

I think to recall that a colleague noticed random initial packet drop bursts with IPERF3 too (and stopped using it).

Regards,

Ruediger
